I put only one pic up at a time, and I start swiping! I gauge how good the pic is by how good looking the girls are that I match with. A couple pics I had I got literally zero matches. Another one I only got very obese girls. Another one I got girls cuter than I thought I could get in real life. It's just kind of fun and really has no purpose other than helping me learn how to take better pictures of myself lol.
